NING-ROOM STOVES.

Specification forming part of Letters Patent N0. 44,383, dated September 27, 1864; antedated September 19, 1864.

T0 tZZ whom it may concern.-

Be it known that I, Jol-1N BAMBER, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Dining-Room Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specitica-tion, in which- Figure l is a vertical central section of my invention, except a portion of the fire-pot P, which is shown in side elevation. Fig. 2 is a top view with the plate K removed, so as to show the arrangement of the flues a, b, and d and the hue-plates f and g. Fig. 3 is a detached view of the firegrate G. Fig. 4 is a transverse section of one of the grate-bars.

Similar letters of reference indicate corresponding parts in the several figures.

The arrows indicate the direction of the draft.

This invtntion consists, mainly, in such an arrangement of the ues in coal-stoves havin g elevated heating chambers or ovens as to produce a more thorough utilization of the heat than is afforded in other stoves of this class, the draft being through the hues, up each side of the oven, over the top, and down the back side, and in the employment of a rotary raker having a horizontal axis, and provided with several wings, which operate through the interstices ofthe grate-bars.

To enable others to make and use my invention, I will describe its construction and operation.

The fire-pot l, which is made of cast-iron, is mounted upon a suitable chamber, A, that rests upon the base B.

The tire-pot is incased by the sheet-iron drum D, upon the top of which is fixed the oven E. This has the ordinary casing or drum, D.

The fire-pot may be east in two or more sections, if desired, joining with vertical seams between the air-fines F, which latter may be cast with the sections or made separate (in a half-due) and attached with screws or rivets; or the plate H may be provided with proper seats to receive the lower end of the ues, and their. upper ends held in place by projections cast on the funnel-plate J. The air designed toburn with the gas enters these flues through perforations in the plate H, and is discharged into the top of the tire-pot through the orices c. There may be a small projecting' guard cast over the openings c to prevent ashes from choking them.

The bars of the grate G may be cast together, as seen in Fig. 3, and each bar cast hollow, as shown in Fig. 4, and open at the inner end; or they may be made open on the lower side, if desired. The object in making them hollow is to strengthen them, and by providing so much airsurface they are less liable to burn out. It will be seen in Fig. 3 that the inner end of the bars is somewhat narrower than the other, which permits the grate to be withdrawn (to -dump the ire) with the greatest ease, because it is freeing itself from the time it starts until it is out.

Theobject of casting the bar h below the upper face of the grate-bars is to prevent coals from catching against it so as to obstruct its withdrawal.

The grate is fitted to slide 011 a ledge (not shown in the drawings) attached to each side of the easing or chamber A.

There may be a latch attached loosely to the chamber at e to clean the ashes from the grate when it is being drawn out. The win gs C of the raker are attached to the shaft s, which, when revolved, throws them through the interstices of the grate, as indicated by the dotted lilies C. This action loosens up the coals and permits the ashes to drop through into the chamber beneath, and allowing no dust or ashes to escape into the room. When the grate is dumped,7 these wings C do very much toward separating the coal and ashes, which separation may be completed by moving the shaft s longitudinali y back and forth a few times, the wings working the ashes through the slots t' into the base B. The curved plate N conducts the coal and ashes to where the wings may act upon them. There may be a similar plate in front. There should be a door in one side of each of the chambers A and B, through which to remove the coal and ashes. There may also be adoor in front, as indicated b v the dotted lines y, to receive the coal; or it may be fed through the oven by opening the door L and removing the griddle M.

When the tire is rst lighted, the damper 0 is opened to permit a direct draft into the pipe l, and after the coal is thoroughly ignited this damper is closed, thus throwing the heat up through the side fines, b and d, over the top ofthe oven, and down the back side before it can escape, which effectually utilizes the heat both for the oven and in the room. The small pipe p, leading from the top of the oven into the smokepipe, is designed to carry off any steam arising from a boiling kettle or othtr cooking apparatus, which is effected by t opening the valve e.

Vhat I claim as my invention, and desire to secure by Letters Patent of the United States, is-

l. The combination and arrangement of thc JOHN BAMBER.
